[0062] The vehicle 100 according to the embodiments of the present application is described below with reference to the accompanying drawings.

[0063] Specifically, as shown in the figure, Figures 1-5 The adjustment of the position of the movable spoiler 1 can be divided into two modes of manual and automatic. In the manual mode, the original position of the movable spoiler 1 is directly in the aerodynamic drag reduction state, that is, the raised mode, and the user can operate the movable spoiler 1 to be raised or lowered through the in-vehicle button if necessary. In the automatic mode, the rain sensor and the vehicle speed sensor can feed back signals to the ECU (Electronic Control Unit) according to the current driving state of the vehicle 100 and the working state of the front wiper, and drive the motor 21 to control the position of the movable spoiler 1 to be raised or lowered in real time.

[0064] When the movable spoiler 1 is in the raised state, the movable spoiler 1 guides the air above the roof to the upper surface of the spoiler, so as to avoid the air being divided into two air flows from the upper surface and the lower surface of the hollow spoiler assembly 10, accelerate the air speed above the roof, thereby reducing the air energy dissipation of the back of the vehicle 100, reducing the overall vehicle wind resistance, and improving the fuel economy of the vehicle 100; when the movable spoiler 1 is in the lowered state, the tail end of the movable spoiler 1 is attached to the rear window glass 20 of the vehicle 100 to be in the same plane, at this time, the air flow can be directly guided to pass through the upper surface of the rear window glass 20, a large amount of air can directly flush the rear window glass 20 of the vehicle 100, increase the air flow speed above the rear window glass 20, and have the effect of cleaning the rear window glass 20 of the vehicle 100 by the air flow, and improve the visibility of the field of view of the rear window glass 20.

[0065] When the vehicle 100 is in driving process, not only can be through manual control, let the active spoiler 1 is always in the state of rise or lower, that is, always keep the mode of aerodynamic drag reduction or the cleaning mode of the rear window glass 20. Also can be through the automatic mode work logic automatic adjustment active spoiler 1 state, in the driving condition, the vehicle speed reaches threshold, the airflow above the roof is accelerated, at this time if the rainfall sensor receives the rainfall level signal transmission to the ECU, drive the front wiper automatic work, the current wiper continuous work 10s above, can be judged as the vision demand priority, at this time the vision priority of the rear window glass 20 is higher than the aerodynamic drag reduction function. The ECU will send control signal to control motor drive gear 22 rotation, drive the active rack 23. The active connecting rod 4 one end is connected with the active rack 23, the other end is connected with the rear end of the active spoiler 1. When the active gear 22 moves downward, the active spoiler 1 can be controlled to lower state, the tail end of the active spoiler 1 is attached to the rear window glass 20, and the airflow is guided to wash the rainwater on the upper surface of the rear window glass 20. When the current wiper stops moving for more than 15s, the priority of the vision priority is lower than the aerodynamic drag reduction function, and the ECU will send control signal to control motor drive, drive the active rack 23 to move upward, and the active spoiler 1 can be controlled to rise state, and the mode of aerodynamic drag reduction is changed.

[0066] The active spoiler 1 device rises and lowers as follows: after each start or ignition of the vehicle 100, the driving motor 21 drives the active spoiler 1 to the fully lowered or fully raised state, so as to check the state information of the device; during the driving process of the vehicle 100, when the driving motor 21 receives the ECU signal, the driving gear 22 rotates in the specified direction, the active rack 23 connected with the active spoiler 1 is engaged, so as to drive the active rack 23 to move downward along the specified direction until it stops at the specified limit state, because there is a movable part cooperation relationship between the active spoiler 1 and the active connecting rod 48, the fixed rod 3 can fix the active spoiler 1, so as to realize the active spoiler 1 in the state of rise or lower, that is, the realization of the drag reduction function and the cleaning function on the upper surface of the rear window glass 20.
